Microsoft Dynamics NAV provides an integrated debugger to help
you check, correct, or modify code so that your application can
build successfully and run as expected.

Activate the Debugger

You can activate the debugger from Microsoft Dynamics NAV and
from Classic Application Server.

To activate the debugger from Microsoft Dynamics NAV, click
Tools, click Debugger, and then click Active. You can also start
Microsoft Dynamics NAV with the debugger active from the command
line. To do this, use the debug parameter: fin.exe
debug.

To activate the debugger from Classic Application Server, you
need include the debug parameter at start-up. For example:

nas debug,startupparameter=”test”,servername=PC0123

If you deactivate the debugger, you cannot activate it again
unless you terminate Classic Application Server and then start it
with the debug parameter.

Note

To be able to activate the debugger, there must be a developer
license file in the Classic Application Server installation
folder.
